尝试使用PhantomJS获取http://gibdd.ru的屏幕截图。
然而，迄今为止没有任何帮助。
我有：
var page = require('webpage').create();
var system = require('system');
page.onResourceRequested = function (request) {
system.stderr.writeLine('= onResourceRequested()');
system.stderr.writeLine(' request: ' + JSON.stringify(request, undefined, 4));
};
page.onResourceReceived = function(response) {
system.stderr.writeLine('= onResourceReceived()' );
system.stderr.writeLine(' id: ' + response.id + ', stage: "' + response.stage + '", response: ' + JSON.stringify(response));
};
page.onLoadStarted = function() {
system.stderr.writeLine('= onLoadStarted()');
var currentUrl = page.evaluate(function() {
return window.location.href;
});
system.stderr.writeLine(' leaving url: ' + currentUrl);
};
page.onLoadFinished = function(status) {
system.stderr.writeLine('= onLoadFinished()');
system.stderr.writeLine(' status: ' + status);
};
page.onNavigationRequested = function(url, type, willNavigate, main) {
system.stderr.writeLine('= onNavigationRequested');
system.stderr.writeLine(' destination_url: ' + url);
system.stderr.writeLine(' type (cause): ' + type);
system.stderr.writeLine(' will navigate: ' + willNavigate);
system.stderr.writeLine(' from page\'s main frame: ' + main);
};
page.onResourceError = function(resourceError) {
system.stderr.writeLine('= onResourceError()');
system.stderr.writeLine(' - unable to load url: "' + resourceError.url + '"');
system.stderr.writeLine(' - error code: ' + resourceError.errorCode + ', description: ' + resourceError.errorString );
};
page.onError = function(msg, trace) {
system.stderr.writeLine('= onError()');
var msgStack = [' ERROR: ' + msg];
if (trace) {
msgStack.push(' TRACE:');
trace.forEach(function(t) {
msgStack.push(' -> ' + t.file + ': ' + t.line + (t.function ? ' (in function "' + t.function + '")' : ''));
});
}
system.stderr.writeLine(msgStack.join('\n'));
};
page.open('http://gibdd.ru/', function(status, b, c) {
page.render('g.png');
console.log("DONE WITH ", status, page);
phantom.exit();
});
以上代码的控制台输出：

似乎这个网页阻止了与PhantomJS相关项目的连接，因为CasperJS不能正常工作。
我尝试将标题更改为：
page.settings.userAgent = 'Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2049.0 Safari/537.36';
并没有帮助。
有没有绕过它？此脚本适用于任何其他网页。
